The Windsor site was located at 1000 Prospect Hill Rd. (the address was later changed to 2000 Day Hill Road) on a 530 acre tract purchased by Combustion Engineering in 1955 from the estate of the Rev. Francis Goodwin of Hartford. Much of the tract was wooded, but ultimately there were more than 30 buildings constructed on the property.

They both used a traveling or screwtype grate at the bottom of the boiler to transport the fuel (lump coal) across the inside of the boiler. As the fuel traveled across the inside of the boiler, it was burned and the ash or unburned fuel would drop into a hopper. These two companies later formed the Combustion Engineering Company in 1912.

The machine used for particle size reduction is called pulverizes or mill. In 1919 at combustion Engineering, Raymond Mill was developed. The early mills were built with maximum capacity of 6 tons per hour. By 1930 the maximum capability of this mill design had been increased to 15 and then to 25 tons per hour.

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...
